Operation steps of rotary evaporator2012-4-16
Open the vacuum pump, if it is faliure, should check each bottle is sealed or vacuum pump itself leaks. A vacuum switch in series to vacuum tube, which can increase the recovery rate and the evaporation rate.
Use of system vacuum, the liquid can suck into the rotors bottle in the feeding port, the liquid height should not exceed half of the rotating bottle. The evaporator can be continuous feeding, you should pay attention to turn off the vacuum pump when feeding to prevent backflow.
The instrument is equipped with specially designed water bath, you must first add water after the power, temperature control scale 0-99 ° C for reference. Due to the presence of thermal inertia, the actual water temperature than the set temperature about 2 degrees on the red, use the correct settings, such as: You need to water temperature 1/3-1/2. After use, unplug the power plug.
Open the electronic control box switch, adjust the knob to the best-evaporation speed. Attention to avoid the fluctuations of the water bath vibration connected to the cooling water.
Recovery of solvent
To open the feed switch to deflate, then turn off the vacuum pump, remove the collection bottle solvent.
1. During installation, each grinding mouth, sealing ring and joints of evaporator should coat with vacuum grease.
2. Heating trough must have water before power on, dry heating is not allowed.
